GASOLINE-DISPENSING DEVICE.

Application filed December 9, 1924. Serial No. 754,868.

The principal objects of the invention are to provide means for automatically draining the dispensing bowl upon the closing of the door but which may be rendered temporarily inoperative if it is desired to operate the dispenser with the door closed or if it is desired to lock the device for a short period withoutdraining the bowl.

A further and important object is to devise a structure which will prevent the operator from manipulating the drain valve while dispensing and thereby cheating the customer.

The principal feature of the invention consists in the arrangement of a removable member between the drain valve of the measuring bowl and a door in the casing whereb the drain valve will be operated automatically on the'closing of the door or said door may be closed without draining the-bowl by manipulating the said removable member.

A further feature consists of the provision of a guard to cover the drain valve spindle to prevent unwarranted operation t ereof.

In the drawings, Figure 1 is a perspective view of a dispensing device to which this invention is applied;

Figure 2 is a art sectional view of a dispensing device s owing the improved drain valve arrangement in side elevation and the 1 door frame in longitudinal section.

Figure 3 is a. perspective view of the drain valve and the co-operating parts inside of the casing.

Figure 4 is a view similar to Figure 3,

showing the means for operating the valve moved out of operating position to enable the door to be locked without draining the owl.

Figure 5 is a full size sectional view of the drain valve.

In the construction of dis ensing device herein shown, the measuring owl 1 is supported at the top of a tapering column 2- which has a door opening in the side thereof to which is secured the frame 3. This frame is formed with a semi-circular pocket extension 4 at the bottom and centrally of the pocket extension are arranged the op positely disposed slots 5 which are closed y the wall of the casing.

A door 6 adapted to close the opening in 1 the frame is provided with a pair of arms 7, the outerends of which are joined by a cross bar 8 which extends throu h the slots 5 of the pocket extension 4 an upon this cross bar is arranged a lug 9 which swings in the semi-circular recess 10 within the pocket structure 4. 0

The dispensing pipe 11 leadin downwardly from the bowl is provide with a T 12, the side branch of which leads-to the dispensing tube connection 13.

A pipe 16 extends downwardly from the T and connects with the overflow pipe 17 from the measuring bowl which leads to the main supply tank.

A valve let is arranged in the pipe 16 immediately below the T 12 and is provided 7 with a spring heldvalve member 15 closing the passage through the pipe 16.

The valve 15 is rovided with a spindle 18 which is arranged in horizontal alignment with the upper portion of the recess 10 in 7 the door frame structure.

An arm 19 is ivotally mounted on the pipe 16 immediate y below the valve and extends outwardly and upwardly past the end of the valve spindle and has a horizontally 30 arranged bushing 20 at its upper end ada ted to move into axial alignment with t e spindle and within this bushing is sl'idably mounted a stem 21 which extends into the recess 10 of the door frame. 35

When the stem 21 is arranged in alignment with and abuts the end of the spingle 18, the lug.9 on the cross bar 8 of-the door will engage the end of the spindle and ush inwardly thereon upon the closing 0 the door, so that when the dispenser is tobe, lockedv up over night, or for any lengthy period, the valve14 will be opened to a low the gasoline to drain out of the measuring bowl. The lug 9 will not enga e the stem 21 when it is moved laterally su ciently far to miss the end of the valve stem 18'.

A forked arm 22 is pivotally mounted on a pin 23 at the inner side of the column 2below the door frame and the fork extends to me arm 19 to one side so that the outer end will not be engaged by the lug 9 of the door as indicated in Figure 4 of the drawings showing the door shut and the spindle 21 extending past the edge of the lug 9.

This provision is made so that the door may be closed in stormy weather, or if the dispenser is being left merely for a short time or if for any reason it is desired to 21 is held normally in a position to e engaged by the lug 9 upon the closing of the door the drain valve will be operated when the dispenser is locked up for the night whereas'the simple action of opening the door closes the valve and allows the filling of the bowl.

. which automatically controls the filling of The dispensing tube is always full of gasoline and normally hangs upon a hook arm the bowl, details of this mechanism being fully disclosed in my pending application filed in the United States under date of December 9, 1924, Serial No. 754,866. 'When the dispenser is to be locked up the valve 27 is lifted off the hook and the operating lever 27"of the valve is placed inside of the standard.

The door frame 3 is formed with two notches 28 and 29, one to receive the valve stem 28" andthe other the valve operating link 29 and when these members are inserted 1nto the notches the door is then closed, thus locking the valve operating lever 27 within the standard 'in such a manner that the valve cannot be tampered with or operated. The device is extremely simple and there 1s nothing of a delicate nature to get out of order. v What I claim as my invention is 1. In a gasoline dispensing device, the

' combination with-the measuring bowl having fill and drain pipes connected therewith, a casmg'enclosing saidjpipes havinga door there mand a spindle actuated drain valve in said drain pipe for emptying the gasoline from the measuring bowl, of a bodily displa cable valve operating membermounted ad acent the drain valve spindle, means for displacing said valve operating spindle to move the same into or out of operative'alignmentwlth the drain valve spindle, and an "operating member connected with said door and actuated thereby. on the closing of the door to engage and operate said movable member when the latter is in its operatively aligned position.

2. Ina gasoline dispensing device, an upright casing having a door opening therein and a frame surrounding said opening, said frame having a pocket below the door opening communicating with the interior of the casing, a door hinged on said frame and having a bar extending through said pocket and forming the hinge pintle'for the door, a measuring bowl mounted above said casing, a spindle operated drain valve arranged in said casing and connected with said bowl, a slidable member normally supported in operative alignment with the valve spindle, a lug on'said bar within the pocket in alignment with the valve spindle for engaging and sliding said slidable member inwardly upon the closing of the door, and means for moving said slidable member out of its normal operative position.
